OIL BURNER;

Application inea July i1, 1923. serial No. 652,139.

T0 all whom t may concern:

Be it known that I, CHARLES A. JAPHET, a citizen of the United States,residing at Seneca, in the county of Nemaha and State of Kansas, haveinvented Oil Burner, of which the followingis a specification. f

This invention relates to an improvement in oil burners adapted to burnany kind of liquidy hydrocarbon fuel, provision being made for theintroduction of water into the fire chamber and its conversion intosteam to mix with the vaporized fuel and increase the efficiency thereofwhen the heavier liquids are used.

The general objects of the invention are i to provide a simple andinexpensive burner structure composed of a minimum number of parts andto provide improved means for introducing and distributing the fuel andwater and for .controlling the mixing thereof after the same has becomevaporized, whereby complete combustion is effected without formation ofsoot and a hot White iiame is emitted.

The invention will be best understood from a consideration of thefollowing detailed description, taken in connection with theaccompanying drawing which illustrates the preferred form of theinvention. p

In the drawing: l

Figure 1 is a vertical section through the burner and the associatedparts.

Figure 2 is a horizontal sectional view substantially on the line 9,-2of Figure 1.

Referring more specifically to the drawing, the invention comprises anair ue 5, frusto-conical in shape, and adapted to rest on a grate 6. Thebase of the flue is surrounded by a rim of cement 7, or the like, forsecuring the same in position, and also preventing any draft of airaround the outside of the flue. erably made in a single casting,includes a central portion 8, which tapers upwardly to a rounded upperend 9, which lis substantially in the same horizontal plane as the upperrimv of the flue 5 and disposed centrally thereof. An oil supply duct 10is disposed centrally of the tapered portion 8, and its lower end isconnected with a suitable oil supply pipe 11. The burner casting alsoincludes a circular base 12 extending outwardly from the base of thetapered a new and useful The burner, which is prefportion 8, and havingconcentric channels 13 and 141 on its upper face. Water is sup-` pliedto the outer channel 14through a water pipe 15, which terminates in a'downwardly turned nippleor street L 16 extendf n to heat up, and thenthe oil becomes vaporized as soon as it leaves the duct 10. The

steam, which is generated from the water in the channel 14, rises up andbecomes thoroughly mixed with the vaporized oil within the cap 16, whichis 'supported in spaced relation above the tapered portion 8 of theburner and the air iiue 5, by means of legs .17 which extend inwardlyfrom the rim 18 ofthe cap and rest on the upper rim of the conical iue5. The cap 16 may be provided with a ring or handle 19 for removing thesame to light the burner. The rim 18 of the cap is provided with aseries of openings 20, through which the flames are emitted. The legs 17support the cap above the air flue and burner so as to' form a chamberin which the vaporized oil and steam become thoroughly commingled withthe air admitted through the flue 5, so that a complete combustion iseffected.

` The water supply pipe 15 does not come in contact with the hot part ofthe burner, and consequently there is little tendency to form limedeposits within the pipe. If these are formed, however, the pipe may beeasily removed and cleaned.

From the foregoing description, it will be seen that the invention isvery simple in its construction, and may be easily installed in anystove or furnace at a very moderate cost. The cap 16 forms a chamberwhere the oil., steam and air become thoroughly mixed, thus resulting ina complete combustion and a hot white dame, which is discharged throughthe openings 20.

While I have shown and described the specific construction of one formin which the-invention may be embodied, it will be understood thatvarious modifications may be made yin theysize, proportion andarrangement of the various parts to adapt the same to the specialconditions under which lll the saine may be installed, and it is myintention to include all such modifications Within the scope of theappended claims.

What is claimed is:

l. In an oil burning device, the combination of an upwardly tapering airflue, a burner member having an upwardly tapered central portion With anoil supply duct discharging at the upper end thereof, an annularextension at the base of the burner member having concentric channels inits upper surface, the inner channel being at the base of the centraltapered por# tion for receiving the oil discharged from the duct, aWater supply pipe leading to the outer channel, and a cap supportedabove the air iiue and spaced therefrom, said cap beingv provided nearitsbase With a series of openings for the emission of the flames and theproducts of combustion.

f 2. In an oil burning device, the combination of a frusto-conical airflue, a burner member having an upwardly tapered central portion with anoil duct discharging at the upper end thereof, the mouth of said ductand the upper edges of the air flue being' in the saine horizontalplane, an annular extension at the base of the burner memlberhavingconcentric channels in its upper surface, the inner channel being at thebase of the central tapered portion for receiving the oil dischargedfrom the duct, and a cap having lugs engaging the upper edge of theynature.
